To all whom it may concern:

Be it known that I, WILHELM REsoH, a citizen of the Swiss Republic, and resident of Binningen, near Basel, Switrerland, have invented new and useful Improvements in Processes for Dyeing, Bleaching, or (like Treatment of Cops, of which the following is a full, clear, and exact specification.

In dyeing, bleaching or like treatment of cops by means of a circulating liquid itis known practice to mount the cops on metal or rubber spindles and so to pack them that the channels produced by this mounting are stopped up by filling material so that there may be uniform dyeing or bleaching of the textile material. It is also known practice 1n dyeing cops without spindles to press them closely together. inarlly pressed cops have been packed on the perforated bottom of the container in such a way that the circulating liquid must pass through the packed cops in a direction at right angles to their longitudinal axes. Or the packing and pressing of the cops has been performed in the container upon the perforated bottom and the container has been so placed that the liquid must pass through the cops in the longitudinal dire'ction.

The present invention relates to the packing and treatment of the cops in the lastnamed manner. In the known procedure, whether in consequence of insufiicient pressure or m consequence of incorrect application of the cops to the perforated walls of the container, an irregular treatment of the cops in the pack is to be expected. According to this invention a thoroughly uniform treatment of the pack is obtained by packing and pressing together the cops on their paper tubes in layers in the container on an unperforated bottom, their treatment with the liquid being in the longitudinal direction between perforated ends of the container, and for insuring the position of the outside cops in the container there is inserted in the end of the paper tube of the cops a short stopper before the packing operation. This stopper forms a retainer for the yarn and a protection for the end of the cop tube. This kind of packing and treatment renders possible a firm and permanently unalterable as well as uniform pressing together of the cops, without additional packing, and prevents the formation of empty spaces-or dead Hitherto the prelimcorners which give rise to irregular passage of the liquid. There is thus obtained throughout the whole a tightly closed packing and even at the extreme ends of the cops a thoroughly uniform treatment of the latter.

After the treatment of the textile material with the circulating liquid the container may be withdrawn and passed to the centrifugal machine for centrifuging its contents.

The accompanying drawing illustrates the process in use on an apparatus for practising the same. Figure 1 is a vertical section through the apparatus; Fig. 2 shows in side elevation a portion of the packing on an enlarged scale and Fig. 3 is an end elevation thereof.

The pack container 0: is packed with cops to be treated, outside the apparatus in which the treatment is to occur. For this purpose it is placed on the unp-erforated side wall which is to the right hand in Fig. 1 upon a support and the cops are laid in it in the horizontal position in layers and pressed transversely to their longitudinal axes, so that they finally form a packing in which all passages between the several cops as well as the longitudinal openings of their paper tubes are tightly closed. A part of this packing is shown in Figs. 2 and 3 drawn to an enlarged scale, from which the mode of laying and pressing together the cops b will be apparent. Before the packing those cops which are to abut against the perforated end walls 0 and d of the container are provided with small short stoppers e which are stuck into the openings of the cop tubes in order to serve as a retainer for the yarn and as a protection for the end of the paper tube as well as to close the opening. These stoppers also serve for insuring the position of the cops in the container during the centrifuging of the pack. When the cops have been packed into the container a the latter,

turned through an agle of 90, is inserted The closed vat which is provided with the usual accessories, such as aapressure gage, safety valve and the like, is fed at m with the liquid under pressure. The liquid is driven from the above downward through the stationary oops I) in the longitudinal direction of the latter and through the filter chambers g, h and leaves the vat at n. The perforated end walls 0, d of the container diistribute the liquid uniformly over the pack and the uniform tight compression of the cops, by means of which all intermediate passages and all dead spaces in the pack for the direct passage of the liquid are closed, insures a uniform saturation of the rfibrous material throughout. When the treatment is complete, the container (1 with the goods in it is removed from the vat f and as may be necessary is passed to the centrifugal machine for the purpose of centrifuging the goods.

What I claim is:

A process for dyeing, bleaching and the like of cops by means of a circulating liquid, consisting in using a container with opposite perforated walls, packing the cops therein under pressure upon an unperforated side wall of the container after having inserted short safety stoppers into the socket openings of the outside cops so that the cops extend perpendicularly to said perforated Walls of the container, then introducing the container with its perforated walls between i a liquid supplying head and a liquid discharging head of a treating chamber and causing the liquid to flow through said heads and longitudinally through the cops of the packing in the container, substantially as and for the purpose described.

In witness whereof I have hereunto signed my name this 4th day of June, 1918, in the presence of two subscribing witnesses.

WILHELM RESCH.
